In the recitation of Hafs by the way of Ash Shatibbiyyah, the lengthening is either 4 or 5 count (not including the natural mudood which is 2 count). I would like to know whether in the recitation of Hafs, but not by the way of Ash shatibbiyyah, one can lengthen to 2 count the alif such as in
Have a blessed month of Ramadan and may Allah double your reward and may He make us remember Him constantly inshallah.

The example given in the question is that of in which the medd letter is followed by a hamzah in the same word. This medd is always lengthened at least four vowel counts in the recitation of Hafs, even in tareeq at-tayyibah, even in the ten qira’aat this type of medd is always at least four vowel counts.
The other type of medd caused by a hamzah, , in which the medd letter is the last letter of a word and the hamzah is the first letter of the next word, as in as in: and we are continuing in reading can be two and even three vowel counts in the reading of Hafs other than tareeq Ash-Shatibiyyah.
Jazakum Allahu khairan for the kind dua’, and may Allah give you equal to that and more.
