Few issues please help

I have a 89 s10 pickup 4cyle 5 speed. I just recently bought it for 400 bucks so it's no gem.

First issue is the dash lights do not work and a few of the gauges don't work. can i just swap the cluster easily or should i replace a bulb?

Secondly when i turn my right signal light on the lights do not blink they just stay lite. i noticed that the voltage meter doesn't move when i turn my right blinker on, but it does when i turn left. i'd like to add that my left blinker works fine, blinks and everything. what could this be?

You can replace the bulbs with the cluster out, but if some of the gauges are not working than the cluster or sending units may be bad? Which gauges do not work?

You have a turn signal bulb burnt out on the right side.
