It's bad to go pass the stock tires index? My tires are 195/60/15. I was wondering if it's alright to go 195/50/15 b/c of financial issue. I know it will messes up your speedo as in my car states that i'm doing 80mph but i'm only going 70mph. thanks

195/50/15 is going to have a bad load rating.

Honestly just get the correct tires.

That is correct. Simply dropping the aspect ratio decreases the size of the air chamber. That reduces the load capacity of the tires. You have to go wider at the same time to do that safely.
