Emulators provide security measures so that usually malware infecting the guest can not escape the emulated environment. However emulators often contain convenient functions for exchanging data with the host and such functions also expose a risk to the host in case a malware had taken over the emulated guest system.
On the other hand the number of malware that can pass the gap from an ARM emulator to a x86 host system is to my knowledge not very large as this is a rather uncommon situation.
But your choice of emulators is not good. Both emulators are primarily optimized for gaming. They often base on old Android systems and I doubt that they are regular updated to include the security patches Google provides.
Therefore installing malware on such an emulator may make it very easy for a malware to take over the whole guest system. And in such a case the chance that it might be able to also jump to the host system increases.
Therefore in my opinion you might better check the Android emulator from Android SDK.
