This is my transfer function but I don't know how to input this on Simulink.

You can insert the Transport Delay block (found in the Library of Continuous function blocks) after the transfer function.
See example here:

If this must be implemented as transfer functions then you will need to copy the transfer function block several times, set the Input Delay differently on each copy, and then add the results all together.
Each individual transfer function can only represent a single exp(), not a sum of exp()

Neither the Transfer Fcn nor the State Space block can model an Input Delay (nor Output Delay) as far as I can tell.

In addition to using a single transfer function along with gains and transport delays as suggested by @Sam Chak, if you have the Control SystemToolbox, you can use one LTI System block and enter the transfer function as the LTI system variable parameter. For example, if
H(s) = 1/(s +1)*(exp(-1*s) - exp(-0.5*s))
then the expression for the block parameter would be:
tf(1,[1 1])*( exp(-1*tf('s')) - exp(-0.5*tf('s')) )
