Are there any differences between
to catch on to someone and to see someone through?
Are they used in specific contexts or do they mean the same?
Sorry, I made a mistake.
For example in sentences like these:
1) If you keep on lying to everyone, they'll eventually see through you/catch on to you.
2) It took me a while, but I finally caught on to him/saw through him.
3) In the end, I saw through him/caught on to him and ended our relationship.
4) He's so charming and sly that few people see through him/catch on to him and realize that he's just a jerk.
Don't they mean exactly the same?? I hope you can help with this.

I wouldn't use "catch on to".
Just because you like it more? or is there a specific reason about it??
In all of your sentences, there is some kind of deceptive behaviour going on, which is why "see through" would be my choice as well.
Take a look at the following example sentences, taken from the Longman Dictionary of Contemporary English:
"Catch on to" is used differently:1 see through somebody/something to realize that someone is trying to deceive you :
I saw through his excuses.
I could never lie to her because I know she’d see through me straight away.
I can’t bluff – she’d see right through me .
2 to begin to understand or realize something catch on to
It was a long time before the police caught on to what he was really doing.
