This is just one way of doing it...

HEXFILES = t1.hex t2.hex
all: $(HEXFILES)
$(HEXFILES):
       echo $(patsubst t%.hex,-DVersion%,$@)

(The % in the first argument matches the number,
the second arg prepends the "-DVersion" to the matched number,
and the third argument specifies the input as the target)

And running this results in:

$ make all
echo -DVersion1
-DVersion1
echo -DVersion2
-DVersion2
