"i cant use timers because there are only 2 of them"

then you have already one more as it was needed.

Simple establish a timer interrupt of e.g. 1ms and count down so many bytes as simultaneous delays you need.

So the only limitation of using only one timer for all delays was only the amount of RAM for the delay counters and the count of cycles between two timer interrupts to handle it all and have enough time remaining for the main loop.
