Yes. This is possible.

You can have different types of trading accounts (Standard Cent, Standard, Pro, Raw Spread, and Zero) on the same server. This facilitates trading on Multiterminal if desired because, in order to trade on it, you need multiple accounts belonging to the same server.

Example:

Say you have a Pro account and a Standard account on the Real2 server. You can log in to the MT4 Multiterminal, choose the Real2 server and place trades on both accounts with a single click.
