Q.Weigela Plant
My friends gave me a Weigela plant last September and it is already 4 feet tall. See picture and do I need to move it to another bigger area. I don’t have much room to move it is the problem.

It doesn't appear that the bed is confined at all. It appears to be in the open, which will be the biggest space possible. Moving it is not necessary and will only cause more stress.
Remove any dead material.
The big issue, here, will be keeping the water level correct to suite the Irises AND the Weigela.
To keep the Iris happy will mean to let the soil dry out thoroughly down to 2 or 3 inches. To keep the Weigela happy will mean to keep the soil drying out further than 3 inches. You have very little wiggle room, but the rain should be sufficient without supplement in most cases.
Fertilization will be necessary once per year.
