Digital signals graph?
In this graph t1 can take any value between (0-4) but in the definition of digital signals it is stated that digital signals can only take finite values but there are infinite number of values between (0-4)

This is a step-wise approximation of the analog signal. I wouldn't call this a digital signal. The transition that happens at t1 is a very fast edge. Little energy is in that edge, as well as all the other edges, as compared to the flat portions.
You seem to be hung up in the edges having infinite states. In digital systems, synchronous logic is commonly used so you determine the state away from the edge where the value is indeterminate due to timing skew, reflections, and other non-ideal conditions. Those that use asynch logic can end up with unruly designs.
