Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Synchronize 25 ESP8266 to start playback of an audio file at the same time
This is a perfect use case for MQTT, e.g. this library for ESP boards. Create a broker on the network (e.g. a Raspberry Pi running Mosquitto, and have all the ESP boards subscribe to a topic. When you want to play a sound, publish a message to the topic, and all of the ESPs should see it very quickly. You don't need to synchronize clocks any more because it's simply based on the timing of publishing a message.

Is there a lowish consistent wireless method for sending variables to an esp32?
For ESPs, the library EspMQTTClient makes it incredibly easy to manage Wifi and MQTT together (with reconnect, OTA, etc)

WiFi disconnects when connecting a MFRC522 to the ESP8266
For the WiFi (and MQTT) library I use https://github.com/plapointe6/EspMQTTClient.

Is there a lowish consistent wireless method for sending variables to an esp32?
If you're just looking for low-latency, I'd go with DMX-512 over UDP packets, and just write your app so if any packets are missed, it picks up with the next one that does arrive.
What are some alternatives?
ESP-Now-Sensor-system-with-WiFi - ESP-Now is used for battery operated Sensors (based on ESP8266, ESP32) sending to a Gateway which also is connected with WiFi to the Internet (at the same time).
