Kvod Harav Shlita,
When Chazal stated that 5 minim satisfy the chiyuv of Marror,what was Chazal's mekor for this?
Bshlama Matzah needs to be from the chamashes mini dagan as Chazal have taught that it needs to be Machmetzis, and only the 5 grains can be bo lidei chimutz.
But by Marror why Davka these 5 minnim, why not any bitter min, was there a kabbalah?
Also,
On motzei Yom Tov Rishon the shamash goes bchashai to people before Maariv to inform mispalleim regarding vsen beracha, why not announce it like any other azkara that needs to be announced?

Our apologies in the delay in answering.
I do not think that the five species of Maror are based on a Kabalah, since the Gemara on Daf 39a presents different lists, not all of them consisting of five species. Moreover, it suggests various other species, which it rejects for a number of reasons. Clearly, the Maror that we are required to eat must fit the specifications mentioned there; for example, it must grow from the ground and it must fall under the category of "Zera'im." Otherwise, it is not eligible.
With regard to your question of Minhag, I am not aware of the Minhag that you refer to. I assume it is one that your Shul initiated. However, I assume that it is based on the prohibition of announcing it publicly in its right place due to creating a Hefsek between Ge'ulah and Tefilah (which is a requirement l'Chatchilah also at Ma'ariv). And to announce it before the commencement of Ma'ariv would sound odd.
Wishing you a Chag Kasher v'Same'ach v'Kol Tuv,

Thank you.
So according to below, may any bitter "herb" be used and an Al Achilas Maror recited.
Also the Halacha below of not announcing it, is cited in the Mishna Berura, (he uses the following terminology, that the shamash, chazzan goes B'chasai before Maariv) I do not have the sefer now in front of me so I can not reference the exact Mareh Makom.
Kol tuv.
"According to below," only the five species listed in the Mishnah may be used with a Berachah, as only they comply with all the specifications mentioned in the Gemara. If none of those species is available, one should eat any bitter herb that one finds, but without a Berachah. Some Rishonim interpret "Maror" (listed among the five) as any other herb, but that is not the Halachah.
As for the Minhag you mentioned, I was not aware that it is brought in Halachah (thank you for pointing it out). I have never seen it practiced, and doubt whether it is.
Chag Kasher v'Same'ach,
Eliezer Chrysler
