I have arduino uno, nano and mega boards with many modules (relay, ir remote, ultrasonic sensors, etc) and they works well together.
I got raspberry pi 3 model b. Can I use my arduino modules with my raspberry pi?

In general, NO.
Arduino works on 5V so any module which outputs 5V levels can't be used. These can often be used with level converters.
Some will work, and I have used a few. You need to study each module.
You can't use all modules. Some of them are incompatible due to the power requirements as @Milliways mentioned. Still, you can connect your prefferable arduino to your raspberry through USB and do whatever you wish through serial port communication - just like you do with your pc.
