My advice is to not look for "strumming patterns" until you're familiar with how to count out the quarter notes of the song and listen for the 'groove' of the song. When you know how to count through a song and can identify the groove, you'll have the strum pattern.
Some people do not like the fact that music is math-based...it's all numbers at its core...so I like to think of music as food. Most people like food. I like food.
All music, every song, is made up of a series of measures. Measures are how every song is divided up into small, typically-redundant timed segments.
So, if music is food (yum!), a song is a long row of pies (pick whatever you like; cherry, lemon, beef, etc...) and each pie is a measure of the song and we're going to cut up the pies to define 1/4 notes, 1/8 notes and 1/16 notes in the measures.
All of the songs you posted above, except one (Indescribable), are all in 4/4 time. Indescribable is in 6/8...more on that later.
4/4 means that every 1 beat is equal to 1 quarter note and there are 4 beats per measure, so there's this reoccurring 1 2 3 4 1 2 3 4 1 2 3 4 ...happening through the measures of the song.
If you can count the quarter notes in a song, you're off to a good start. It's like taking that row of pies (remember, food?) and cutting each one into 4 equal pieces. Each slice is one beat or quarter note.
Start with the song "Mighty to Save".
In the chorus, many of the words drop right on the quarter notes:
Sav-Ior, He can Move the MounTains, my God is Mighty To savE, He is Mighty To savE, for...
1----2----3---------4----------1-------2-----3-----4--------1--------2-------3--4-----1---------2-------3-4-----
...E-Ver, Author Of salVaTion, he Rose and Conquered The gravE, Jesus Conquered The gravE
--1--2----3--------4------1---2---3----4------------1---------------2----------3-4-------1--------------2-----------3--4----
I can't stress enough how important it is to be able to count and feel the basic quarter note beat of a song.
Practice it with every song that you can until it becomes natural.
Once you know that, you can find the groove of a song. The groove is the feel of the rhythm and how it's established around the quarter notes. Sort of like how we further slice up the pieces of pie into smaller sections.
Again, "Mighty to Save" as an example (the original live Hillsong United version), it has two distinct grooves:
the verse has a 1/16 note feel w/ accents and the chorus and bridge have a solid 1/8 note traditional 'rock' feel.
1/8 and 1/16 notes are just smaller divisions of the 1 2 3 4 - beat I described above and it could be displayed like this:
1 . - . 2 . - . 3 . - . 4 . - .
The numbers are the quarter notes, the dashes are 1/8 notes and the dots are the 1/16 notes.
You'd count it as follows:
1/4 notes; 1 2 3 4
1/8 notes; 1 and 2 and 3 and 4 and
1/16 notes; 1 e and a 2 e and a 3 e and a 4 e and a
The quarter note count remains constant for all three...the original 4 slices in the pie remain unchanged...but the space between the quarter notes gets identified and counted...we slice the pie into smaller equal sections.
The pie didn't grow, it didn't get faster, it didn't stop practicing with a metronome (hint!)...it just got divided up more.
On the verse of MtS, the drums are playing 1/16 notes w/ accents, the lead guitar is playing a redundant 3-note riff in 1/16 notes, the other lead is playing choppy 1/16 note chord fragments and the acoustic guitar is strumming 1/16 note chords. Even the bass is playing 1/16 notes!
It gives the song the feel of fast, steady motion without the tempo having to be too fast. The song is only 73 beats per minute...relatively slow to mid tempo for a song...but the 1/16 notes played in the verse help move it along without feeling like it's a ballad.
On the pre-chorus, chorus and bridge, the drums play an 1/8 note feel. Listen to the high hat; it goes "1 and 2 and 3 and 4 and". The electric guitars play more of an 1/8 note rhythm, but the acoustic plays a combo of 1/8 and 1/16 note strums.
This is where being able to count the quarter notes and divide them up into smaller pieces comes into play.
If you can count "1 2 3 4" and then "1 and 2 and 3 and 4 and" and finally "1 e and a 2 e and a 3 e and a 4 e and a" then you should be able to hear/learn/develop a lot of strum patterns.
Oh, there are 1/32 and 1/64 notes, too, but don't worry about cutting the pie into such small segments right now. Save those for people who are on a diet...
There's a lot more to be said about tempo/feel/groove than this, but it's essential that you understand these basics first.
"Blessed by Your Name" is a very simple 1/8 note strum, down-up-down-up with each down being the 1/4 note and each up being the 1/8 note.
If you listen to the song, the high hat should be playing 1/8 notes. Listening to the high hat and snare are good ways to get the feel/groove of a song.
Again, 1 and 2 and 3 and 4 and = down up
down up down up
down up
I'd probably play the 2 and 4 downstrums a little harder/heavier to be in sync with the snare drum, emphasized in bold above.
"Indescribable" is in 6/8 time.
1/8 notes get the beat and each measure is 6 beats.
It's counted 1 2 3 4 5 6 1 2 3 4 5 6 etc...
The acoustic guitar strums in 1/16 note beats.
1 and 2 and 3 and
4 and 5 and 6 and
Every number is a downstroke, every "and" is an upstroke and stronger accents are played on the 1 and 4.
The song has a VERY fast feel to it.
I have a youtube video lesson of this song on my page, but I noticed that you can't see my strumming hand at all in the video.
I'll go fire the director...

Hopefully, all of these words have made some sense to you and anyone else reading them.
